CAN on REGEPTACLE FOR STORAGE BATTERIES.

'Patented July 2,3, 1907.

Application led August 16,1904. l Serial No. 220,912.

To all whom it ymay concern;-

Be it known that I, THOMAS A. EDrsoN, a citizen of the United States,residing at Llewellyn Park, Orange, countyv of Essex, Stateof NewJersey, have invented lcertainnew and useful Cans or Receptacles forStorage a Batterlesgof'which the following is a description.`

MYv invieiitiorf relates to metallic cans or receptaclesforfstbrpgeibatteries, lparticularly of the type invented fbyrnim'wherein iron or nickel is used as the active mail) ,terialst y Atthe present time, the cans Which are com- -xnercially used for thispurpose are composed of very thin sheet steel, carefully nickel-platedwith corrugaf 'tions formed in the side and end faces to secure thenecessary stiffness, the joints at the side seam and at the l 5 top andbottom, being made liquid and gas tight by the use of an insolublesolder. Diiiiculty has been experien'ced in using a solder for thispurpose owing to the fact that the joint sometimes becomes affected byreason of local electrolytic action between the solder and the adjoiningmetallic surfaces, and this` difiiculty is more likely to occur at thetop of the can, since the top requires to be secured in place after theelectrode plates 4have been introduced in position, and consequentlytlie'same opportunity is not presented for making as good a mechanicaljoint at the top as at the side seam or The object of my presentinvention is to provide an improved can or receptacle for a storagebattery, wherein the difficulty referred to may be overcome.

'30 To this end the invention consists in making the can or receptaclewith a ltop welded in place, so that no solder whatever will benecessary, and preferably the invention consists in a can or receptacle,whose side seam is welded, and whose bottom is also Welded in position.

In order that the invention may be better understood,

attention is directed to the accompanying drawings forming a part ofthis specification, and in which Figure l is a vertical sectional view,showing the can or receptacle in its preferred form. Fig. 2, a crosssec- 40 tional view showing the side seam, after it has been welded, butbefore it has been turned down, and Fig. 3,

a corresponding view showing the side seam in its nal ents heretoforegranted. To provide for the necessary stiffness, corrugations 2-2 may beformed in the side and end faces of the can. lThe top 3 is providedwith.

Letters Patent, led'on the 21st. day of July 1904, Se-

rial No. 217,538 and wherein a rotating carbon is caused to progressslowly around the line of the seam to form an arc between the carbon andthecan, and by which the welding may be accomplished. In this way, thewelded portion is superficial and extends only a short way down from theupper edge of the flange 4, so that when it becomes necessary to removethe top vfor any reason, this may be done merely by ling-off the weldedportion, so as to free the top. The flange 4 is sufficiently deepto-allow this to be done a number of times. The bottom 6` is providedwith a down tiuned flange 7, and is also preferably welded in positionlike the top ,along theline 8. The body l is formed with a seam betweenthe fianges 9 and 10,which `seam is locatedl at one side of the line ofcorrugations,'as shown, so as not to interfere with the same. vThefianges'9 and 10 are also preferably Welded along the line 11,andthereafter the flanges 'are turned down as Fig. 3 so as not to interferewith the symmetrical appearance.

Obviously, the bottom and side seams may be welded in any other suitableway, but preferably by the process and apparatus described in myapplication above referred to.

Having now described my invention, what l claim as new land desire tosecure by Letters Patent, is as follows: f

1. A metallic can or receptacle comprising a bodynnd a anged top, saidiiange being welded to the body along its edge only, whereby the top maybe separated from the body by the removal of a portion of the ange,substantially as set forth.

2. A metallic can or receptacle comprising o. body and a flanged bottom,said fisnge being welded to the body along its edge only, whereby thebottom may be separated from the body by the removal of a portion of theflange, substantially as set forth.

This specification signed and witnessed this 10th day of August 1904. jv
